Skipped Faunus 0.2.y line in order to synchronize with Titan 0.3.z
Bumped to support Titan 0.3.0
Bumped to support Hadoop 1.1.2
Moved IdentityMap to base directory as changed in Pipes 2.3.0
Refactored the means by which MapReduce test cases are written
FaunusVertex property value serialization support using Kryo 2.2.1
FaunusVertex01 provides history deserialization support for Faunus 0.1.z → Faunus 0.3.z conversion
Moved util.MicroElement classes into respective FaunusElement inner classes
Added numerous test cases for file-based RecordReader formats
Added ScriptInputFormat to support the arbitrary reading of an HDFS file lines into a FaunusVertex
Added ScriptOutputFormat to support the arbitrary writing of an HDFS file line from a FaunusVertex
Introduced the faunus.pipeline property namespace for properties that are global to the pipeline
Added support for vertex-centric “filters” for isolating subsets of a graph InputFormat
Fixed a severe bug in the propagation of Configurations throughout a Faunus job sequence (EmptyConfiguration)
Renamed GraphSONUtility to FaunusGraphSONUtility to avoid name conflicts with Blueprints
Added EdgeCopyMapReduce to support graph transpose for bidirectional edges
FaunusGraph now implements Configurable and thus getConf() instead of getConfiguration()
Removed unnecessary combiner steps when the combiner only groups messages without compressing them
